TUBULAR CCNVEYER FOR FEAT-COLLECTING MACHINES.

Specification of Letters Patent. I

Patented June 4, 1907.

Application filed September 24, 1906. Serial No. $6,062-

T0 aZZ'whom it may concern:

by the lodgin I of America under Number 782,260 on the 14th. February, 1905, and the object of the present invention is todevise a means whereof peat in the lower internal periphery of the tube may be 0bVl8.t(- d &nd' thus" insure the complete discharge of such peat continuously and it consists essentially of one or more convolute or spiral wings secured to the interior of the tube preferably in sets of two located opposite to each other and havin preferably the thread and pitch as hereina or more particularly explained.

Figure 1, is a perspective vi v of portion of my peat collecting machine 'showi n the ima provements in the tube thereof.'

ig. .2 is an enlarged perspective detail of portion of the tube showing my improvement.

In the drawings like letters 0t reference indicate corresponding arts in each figure.

A A are two convoute or spiral win s of an annular cross section, Tnebase' of w ich is made to conform to the interior of the tube and is secured thereto, and the opposite side of which extends into the tube and forms a thread. The pitch of the thread of the spiral or convolution is preferably a lon pitch and; I also preferably provide two 0 the wings located opposite to each other, although one or anynumberI may find preferable.

I have shown in Fig. 1, two sets or pairs of spirals, but it will be understood that I may provide as many sets and at any desired distances apart in the tube as may be most conducive for the object I have in view. viz. .to

. prevent the cat from lodging in the bottom referred to.

of. the interior of the tube throughout its .lengtlifand thus make the discharge of such peat more difficult as well as serving toblock the free discharge. p

It will be seen that the discharge end of my tube isconnected to a fan casing as described in m former patent herembefore he fan in such casing causes a suction through the tube, thereby drawing the peat through'the same and discharging it from the casing in the usual manner. It is to-be noted, therefore, that my tube is stationary.

The operationis as follows: The'continual suction of the air and peat therewith through the tube efiected by the spiral wings serves to not only ive a continuous twist'or rotary motion of t e air as itpasses through the tube,-bu t necessarily to the peat carried by the air as itpasses through the tube and by this means the lodging of peat in the bottom of the tube is effectually prevented. Formerly without the wings the fine particles of peat would lodge or drift into the tube and as the tube was at an incline would finally fill up the tube, and thereby prevent any more peat from passing upwardly through the same. In practice I have found formerly on account of this defect the machine became practically inoperative, but by'the in:

troduction of these wings the continuous even feed of the peat is assured.

By such a device as I describe I find that thefdischarge of the peat is effectually facilitated.

. Although I describe my invention as applied to the discharge of peat it will-be understood that it may with equal facility be applied to other analogous purposes.

What I claim'as my invention is:

1. 'In a' tubular conveyer for peat collecting machines, the combination with a fan casing and fan and non-rotatable tube extending from the fan casing, of a spiral wing secure'djto theinner-nperlphery of the tube in such a manner that the pitch of the spiral will be long and extend some distance along the inner periphery as and for the purpose specified.

21- In a tubular conveyer for peat collecting machines, the combination with the tube, of spiral L'shaped in cross section, said spiral wings I eing oppositely secured to the inner periphery ofthe'said tube, in such-a "manner that the pitch of the spiral will be long and extend some distance along the inner periphery of the said'tube, substantially as described. j 1
